I have a couple of the patterns down well enough to use them in some of my songs like the one I sent you a little while ago. Then I got “If You Could Read My Mind” by Gordon Lightfoot stuck in my haed and “had” to learn his picking pattern in that song to make it go away. While not a true “Travis” pattern, it has proven useful. Hanson’s book paired with a metronome has been the way to go for me.
